' 14 Claim.

This invention relates to transfer mechanism and particularlyto transfermechanisms for calculating machines of that class in which subtractingand adding operations are carried out in conjunction with totaling andlisting operations.

An object of my invention is to carry out the transfer operationdirectly, and to provide a step motion for such operation, operatingpositively and functioning throughout the whole width of the machinewhen such functioning is necessary with simplification of theconstruction as compared with other means now employed for this purpose.

In carrying out my invention I provide reciprocating bars each having aplurality of cam surfaces, which are located between the actuating barsof each order. The accumulating pinion of each order is provided with acam which actuates a pivoted member when the pinion associated therewithis rotated through its zero position.

The pivoted member is moved to a position in which a sliding member incontact with the cam surfaces operates the adding pinion lock of thenext higher order to move its accumulating pinion through one number toeil'ect the undercarry or carry-over as the case may be, depend ing onwhether the transfer mechanism is being used to effect subtracting oradding operations. For convenience, I am illustrating the invention asbeing used in effecting subtracting operations.

A better understanding of the invention may be had by reading thefollowing description together with the accompanying drawings, of whichFig. 1 is a fragmentary, vertical, longitudinal, sectional view throughthe machine showing the relation of the keyboard actuator bars and subtracting mechanism in normal position;

Fig. 2 is a partial fragmentary, vertical, longitudinal, sectional viewshowing the subtracting mechanism after the subtracting lever (notshown) has prepared the mechanism for the subtracting operation;

Fig. 3 is a partial fragmentary, vertical, longitudinal, sectional viewshowing the subtracting mechanism prepared for the undercarry;

Fig. 4 is a. partial fragmentary, vertical, longitud nal, sectional viewshowing the subtracting mechanism, after the undercarry has beeneffected;

Fig. 5 is a fragmentary vertical transverse section on the line 5-5 ofFig. 2 showing the undercarry mechanism; and

Figure 6 is a fragmentary side elevation on an enlarged scale of one ofthe restoring frames.

It will be understood that wherever I speak of "front or forward it willmean in relation to the person facing the keyboard and rear or rearwardwill be away from such person. In other words, the left hand end ofFigure 1 represents the front of the machine. Also, when I speak ofright" or left it means to the corre sponding direction of the personwho faces the machine.

This is a division of my co-pending application Serial No. 49,565,filedAugust 11, 1925, now Patent No. 1,823,859, and in designating thevarious features in the drawings of the present application I have usedreference numerals similar to those used in the earlier application indesignating like parts.

In Fig. l, I have shown, as described more in detail in the priorapplication, a longitudinal section of a keyboard in which therespective keys 1 to 9, inclusive, of the columns making up thekeyboard, are supported and guided in suitable horizontally spacedplates 10, 11 and 12. Actuator bars 13, of which there is one for eachcolumn of keys, pass through and are guided in slots or cut-out portionsformed in. and adjacent the lower ends of the stems of the respectivekeys of each column, as shown more particularly in Patent No. 1,823,859.The portions of the actuator bars which pass through the aligned slotsin the keystems are provided at points adjacent their top and bottomedges with laterally projecting stops as indicated at 14, 15, 16 and 17.These stops are adapted to engage certain of the keystems of the keys intheir respective columns and thereby limit the longitudinal movement of.the actuator bars 13, all as described more fully in Patent No.1,823,859.

On the rearward ends of the actuator bars 13 are toothed racks 3'7(Figs. 1, 2, 3, and 4) and near the forward end of each is a cut or slot38 for the actuator bar locks. Further rearwardly there is another cutor slot 39 for zero locks to be presently described. The actuator barlocks consist of a series of pivoted members 40, etc., one for eachactuator bar. 7 Pins 52, etc. or similar laterally-projecting membersare carried by the actuator bar locks to engage with the arms 56, etc.,which are carried by and move with the keystem locks 29. The upper edgeportions of the actuator bar locks are formed of two plane surfacesmeeting at an angle to each other so that flat springs 60, etc. maypress against one or the other of these surfaces, as desired, and thusserve to retain the actuator bar locks in their locked or unlockedpositions.

The zero locks, one of which is indicated in Fig. 1 at 64, are pivotallymounted on and secured to the keyboard frame. Fixed to the rear end ofeach keystem lock is an arm 76, etc. which is adapted to contact withthe pin 80, etc. on one side of the adjacent zero lock. The operation ofthe actuator bar locks and of the zero locks on depression of keyseither in their respective columns or in adjacent columns is describedin greater detail in Patent'No. 1,823,859, and for a fullerunderstanding of such operation attention is directed to that patent. Asis brought out more fully in Patent No. 1,823,859, the actuator barlocks and the zero locks co-act to insure the printing of zeros forthose columns in which no key has been depressed that are located to theright of the column of highest order in which a key has been depressed,and to inhibit the movement of any actuator bars to the left of suchcolumn of highest order in which a key has been depressed. I

As before mentioned, each actuator bar 13 has a rack, such as at 37, onits rearward end which engages with a printing segment 84 by means ofthe toothed portion 85. These segments are preferably mountedon a commonshaft 86' with proper provision for retaining them in alignment with theactuator bars. In one side of each of the printing segments 84 is theprinting portion 86 which I illustrate as having type on the edge to actin conjunction with the ribbon 8'7 and the movable platen 88; thisplaten having a shaft 89 and being shiftable through the medium of anysuitable mechanism known to those skilled in the art. The printingportion 86 of the printing segment 84 would ordinarily have elevendivisions; one blank and the others composing type from 0 to 9consecutively.

It will be noted that the printing portion 86 is at a greater distancefrom the shaft 86 than is the toothed portion 85. This is done in orderto provide a greater degree of movement for the printing portion 86 fora given movement of the toothed portion 85 and I can vary thisproportional movement for any given conditions to be met. The ribbon 87may be one applied and actuated by any of the means and methods wellknown in the art while equally common means may be used to force theplaten 88 against the type faces in the printing operation. Theaccumulating pinions 90 and the accumulating pinion cams 91 movetogether and are mounted in a pivoted frame 92, the pivot beingindicated at 93 and the shaft for the cams and pinions at 94. Forward ofthe accumulating pinions are the pinion locks 95, mounted on the shaft96 and having teeth into which the teeth of the accumulating pinionsfit. Also, beneath each pinion lock is a stop 98 which acts inconjunction with a cam lock or other suitable means 99 by which thispinion lock may be held against movement in the adding operations andreleased in order to swing about the shaft 96 in the subtractingoperations; it being understood that the cam lock means 99 is operatedby the same means that is used to change from adding or subtractingoperations. Pivoted on the extensions, such as 100, of the frame 92 arethe adding step levers 101, the upper ends of which are adapted to seatupon the straight faces of the corresponding accumulating pinion cams91' and the lower ends of which'are adapted to engage with stops 102 onthe actuator bars 13 adjacent to the racks 37; it

being understood that each step lever operates between its cam and theactuator bar of next higher order.

Below the actuator bars and operated by a main shaft (not shown) is therestoring frame shaft 103 upon which are the restoring frames 104. Thereis one of these frames for each actuator bar of the general shape shownin Fig. 1 and having on their upper ends studs or bearings such as 105which contact with the actuator bars 13. These restoring frames arekeyed to the shaft 103 by means of the spline or key 103a, but thekeyways 106, are enlarged so that the restoring frames 104 have acertain extent of movement independent of the shaft 103 for a purpose toappear hereafter. Passing around each of the restoring frames is aspring 107, the ends of which are held in holes through the shaft 103 sothat this spring acts as a resilient coupling between the shaft 103 andthe restoring frame 104 within the limits of the keyway 106.

In an adding operation, the actuation of the main shaft causes frames104 to move rearward releasing the actuator bars 13 whereby they moverearward moving the printing segments 84 to the positions to print theamount registered on the keyboard of the machine. During the rearwardmovement of bars 13 the pinions 90 are out of engagement with thetoothed portion 85 and in engagement with the locks 95. At the end ofthe rearward movement of bars 13, frames 92 are rocked to bring thepinions 90 into engagement with the toothed portions 85 and out ofengagement with the locks 95. On the restoring movement of the machine,the bars 13 move forwardly and accumulate the total on the accumulatingpinions all as more particularly described in my prior Patent No.1,823,859.

In Figs. 1 to 4 the subtracting mechanism is shown which operates as adirect undercarry throughout the machine. For each accumulatin pinioncam 91, there is a subtracting step lever 108 which is pivoted at 109,the slot 110 in which the pivot acts being large enough to permit ofsome vertical movement of lever 108 against the tension of the spring111. The upper end of this lever 108 has a cam surface 112, whileslightly below this portion of the lever is a pin or stud 113 extendingunder the pinion lock 95 of the next higher order (Fig. 5). Extendingfrom the lower edge of pinion lock 95 is a projection 9'1 (Fig. 2)having a seat 118' adapted to engage the stud 113 under circumstanceswhich will appear hereafter. Adjacent to each of the subtraction steplevers 108 is a lever 114 arranged to move vertically on the pins 115and, 116 and normally held upward by the tension of spring 117. The pins115 and 116 are carried by the extension 92a of the frame 92. On theupper end of the undercarry lever 114 is a seat 118 while pivoted on thelower end thereof is an extension arm 119 pivoted at 120. The extensionarm 119 can swing freely in the direction toward the rear of the machinebut not in the opposite direction on account of the stop 122 at the topof the extension arm 119 which engages the front edge of the lever 114.At the lower extremity of extension arm 119 is the cam roller 121.Between the actuator bars 13 at the rear portions thereof are thesubtracting bars 123 each having a series of cam contours on its upperedge which in this instance are shown as being approximately portions ofcircles adapted to conform to the cam roller 121. At the forward ends ofthe subtracting bars are forked portions in which rides the bail 141carried by arms 142 extent.

which in turn are keyed to the actuating shaft 103. These subtractingbars have a reciprocating motion each time that the actuating shaft 103is operated, but neither the rate nor extent of their movement need bethe same as that of the actuator bars 13 as obviously they may move toany extent in any time relation within the range of movement of therestoring frame, or separate actuating means may be provided therefor orthe extent of the movement thereof may be varied by varying the lengthof the arms 142. Also it should be understood that the lever 114operates between the subtracting bars 123 of one order to the pinionlock 95 of the accumulating pinion of the next higher order.

The subtracting operation is illustrated in Figs. 1 to 4 and at theoutset it will be understood that here the times of engagement anddisengagement of the accumulating pinions are opposite to that in theadding operations. That is, the actuator bars which have been releasedby their actuator bar locks move rearward to their zero position atwhich point their corresponding pinions engage with their printingsegments and disengage from those printing segments before the actuatorbars start to move to the front. The normal position of the subtractingmechanism is as shown in Fig. 1. When the subtracting lever (not shown)is thrown in, the various parts of the machine assume the relativepositions in Fig. 2 where the accumulating pinions have gone intoengagement with their printing segments; the subtracting step levers 108have been carried rearwardly, the cam locks 99 have moved to free thepinion locks 95 and the addingstep levers 101 have been thrown up totheir inoperative position by suitable means not shown. When theoperating handle is brought forward, the actuator bars move rearward,the accumulating pinions are rotated in a clockwise direction and theproper numerals are brought to the printing line and the number to besubtracted is printed. As heretofore described, the subtracting bars 123have a movement to correspond in time with the actuator bars 13 althoughthis movement may be of greater or less So that, in the movement justdescribed, these subtracting bars will move rearward with the actuatorbars. Also in the clockwise rotation of the accumulating pinions andtheir cams, some of the subtracting step levers 108 will remain as inFig. 2 while those subtracting step levers whose cams have rotatedthrough the zero position will be thrown back as in Fig. 3 so as tobring the studs 113 of the subtracting step levers 108 into registrywith the seats 118 of the projections 97 of the locks 95. As shown inFig. 3, the studs 113 will at this stage have moved slightly past a fullseating position with respect to the complementary seats 118 of thelevers 114. At the same time the levers 114 will have been forceddownward in the path of the subtracting bars 123. As the subtractingbars move rearwardly no further effect is produced on the levers 114because the pivoted knuckles or extensions 119' on these levers allowthe rollers 121 to swing freely rearwardly whenever struck by the camsurfaces of the subtracting bars. Of course, those levers 114 which havenot been depressed, as in Fig. 2, will not contact with the subtractingbars in any way and no undercarry will be effected. When the rearwardmotion of the actuator and subtracting bars is complete and theundercarry to be made, the accumulating pinions first leave theirprinting segments and enter the locks and the actuator and subtractingbars start to move to the front, As the accumulating pinions enter theirlocks and the levers 114 associated therewith are carried'forwardly theseats 118 of those levers 114 that have been depressed are moved intofull seating position beneath the studs 113 as shown in Fig. 4. In thefirst part of the forward movement of the adding and subtracting bars,the accumulating pinions being in their looks and the printingsegments'free, the cam surfaces of the subtracting bars associated withdepressedlevers 114 will contact with the rollers 121 of the levers 114and as these rollers cannot move forward because of the stop 122 on thepivoted extension 119, the lever 114 will be forced upward to carry withit the subtracting step lever 108 and the lock 95. This movement of thelock 95 rotates the accumulating pinion one step (Fig. 4) to effect theundercarry. It will be understood that this acts from one subtractingbar to the pinion of next higher order for the reason that the stud 113on the subtracting lever 108 of one order co-operates with the extension97 on the pinion lock 95 of the next higher order.

Furthermore, where the number to be subtracted requires that several ofthe adding pinions be rotated through their zero positions, but does notrequire an undercarry in any case through more than the next higherorder, the undercarry in the case of all the pinions occurssubstantially simultaneously throughout the machine because eachsubtracting bar being operable by the bail 141 moves at the same timeand affects its corresponding lever 114 which in turn operates itsassociated lever 108, so that all columns of the machine may be afiectedwithout having to regard the factor of time in which the operation takesplace.

However, there are some instances where the Suppose, for example thenumber in the machine is 1004 and it is desired to subtract from this,the number, 7 6. As previously described the accumulating pinion in theunit columnwill rotate in a clockwise direction, through the zeroposition to the position 8. At the same time the accumulating pinion inthe 10s column will likewise rotate through the zero position to theposition 3. As these pinions pass through the zero positions therespective step levers 108 and levers 114 associated therewith arestepped to the positions shown in Fig. 3 preparatory to the undercarrywhen the subtracting bars 123 return to their normal positions. Thereturning subtracting bars 123 eifect the undercarry in the mannerheretofore described bringing the pinion in the tens column to 2 andthat in the hundreds column to 9. But in the undercarry to the hundredscolumn the accumulating pinion for this column has itself passed throughthe zero position and has pre-- pared the lever 108 associated with itfor an undercarry into the thousands column which is effected by itsassociated subtracting bar 123 on its return stroke although slightlysubsequent in time to the undercarry of the preceding columns. Thenumber now set up on the accumulating pinions in these four columns is0928 which is the correct result, and as the zero is to the left of thenumber. its printing is prevented in the totalling operation by means ofmy novel cipher lock which is the subject of my copending application,Serial No. 701,283, filed December 7', 1933.

After the lock 95 has been pivoted upwardly in effecting the undercarry,the roller 121 of the lever 114 associated therewith will continue toride up and down each successive cam on the subtracting bar disposed inits path until the return movement of the subtracting bars is com- 5pleted. However, this has no efiect on the undercarry as the lock 95remains in its raised position in looking engagement with its associatedaccumulating pinion until the pinion frames are again swung to carry theseveral accumulating pinions out,of engagement with their associatedpinion locks in the next succeeding adding or subtracting operation asthe case may be. i

It will be noted that the subtracting mechanism just described couldequally well be used for adding operations by substituting it for theadding mechanism described in my Patent No. 1,823,-
